Abstract

Un récipient (10) à usage unique de mélange et de distribution de deux composants qui y sont contenus comprend une membrane (20) agencée à son intérieur qui divise le récipient en deux chambres (30, 31) dans lesquelles sont contenus les composants séparés. Il faut pour assujettir cette membrane (20) une bride dépassant de la paroi du récipient (10), dont l'aspect est peu esthétique et qui augmente en outre le volume de l'emballage et le rend plus coûteux. Pour éviter cet inconvénient, un récipient (10) sous forme d'emballage pressurisé à soupape de distribution (12) comprend une membrane (20) assujettie de manière étanche à l'intérieur du récipient (10) et conçue de telle manière qu'une force déclenchée par une pression différentielle introduite dans les chambres (30, 31) ouvre la membrane (20).A single-use container (10) for mixing and dispensing two components contained therein comprises a membrane (20) arranged within it which divides the container into two chambers (30, 31) in which the separate components are contained. To secure this membrane (20), a flange protruding from the wall of the container (10) is required, the appearance of which is not very aesthetic and which also increases the volume of the packaging and makes it more expensive. To avoid this drawback, a container (10) in the form of a pressurized package with a dispensing valve (12) comprises a membrane (20) sealed in a sealed manner inside the container (10) and designed in such a way that a force triggered by a differential pressure introduced into the chambers (30, 31) opens the membrane (20).

Description

Behälter zum Mischen und Entnehmen von zwei darin enthal- tenen Komponenten Container for mixing and removing two components contained therein
Die Erfindung betrifft einen zum einmaligen Gebrauch be- stimmten Behälter zum Mischen und Entnehmen von zwei darin enthaltenen Komponenten mit einer im Innern angeordneten Membran, die den Behälter in zwei Kammern, in denen sich die getrennten Komponenten befinden, teilt.The invention relates to a container intended for single use for mixing and removing two components contained therein, with a membrane arranged inside, which divides the container into two chambers in which the separate components are located.
Bestimmte Produkte wie z.B. Haarfarben oder Kleber bestehen aus zwei Komponenten, welche getrennt gelagert werden müssen und erst unmittelbar vor dem Gebrauch miteinander vermischt werden. Im allgemeinen geschieht das Mischen der in zwei einzelnen Packungen befindlichen Komponenten da- durch, dass die Komponente der einen Packung zu der Kompo¬ nente der anderen Packung überführt wird, wobei selbstver¬ ständlich die Packung der zweiten Komponente ein ausrei¬ chendes Volumen zur Aufnahme beider Komponenten und gege¬ benenfalls zusätzlich ein Freivolumen zur Erleichterung des Mischvorgangs aufweist.Certain products such as Hair colors or glue consist of two components, which must be stored separately and only mixed with one another immediately before use. In general, the components in two individual packs are mixed by transferring the component of one pack to the component of the other pack, the pack of the second component, of course, having a sufficient volume to accommodate both Components and, if necessary, additionally a free volume to facilitate the mixing process.
Es ist ein druckloser Behälter der eingangs genannten Art bekannt, in dem die einzelnen Komponenten durch eine Alumi¬ niumfolie voneinander getrennt sind. Zur Vermischung der Komponenten erfolgt ein Durchbruch der als Membran wirken¬ den Folie über ein an den flexibel gestalteten Boden ange¬ koppeltes Formstück, welches durch Fingerdruck betätigt wird, so dass die Komponenten von einer Kammer in die an¬ dere gelangen können, wobei die Vermischung erfolgt. Die Ausbringung des Gemisches geschieht ebenfalls durch Finger¬ druck auf den flexiblen Boden.A pressure-free container of the type mentioned at the outset is known, in which the individual components are separated from one another by an aluminum foil. To mix the components, the membrane acting as a membrane breaks through a molded piece which is coupled to the flexibly designed base and is actuated by finger pressure, so that the components can get from one chamber to the other, the mixing taking place he follows. The mixture is also applied by finger pressure on the flexible base.
Derartige Behälter haben den Nachteil, dass zum Anbringen der Membran ein aussen am Behälter überstehender Flansch erforderlich ist, der für den Verwender derartiger Behälter einen optisch unschönen Eindruck erweckt und darüber hinaus das Volumen der üblicherweise vorhandenen umhüllenden Ver¬ packung des Behälters zum Mischen in unwirtschaftlicher Weise vergrδssert.Such containers have the disadvantage that a flange projecting from the outside of the container is required to attach the membrane, which is intended for the user of such containers gives an optically unattractive impression and, in addition, increases the volume of the usually existing enveloping packaging of the container for mixing in an uneconomical manner.
Aufgabe der vorliegenden Erfindung ist es, diesen Nachteil zu beheben und die durch bewegliche mechanische Mittel be¬ wirkte Durchtrennung der Membran zweckmässig zu ersetzen.The object of the present invention is to remedy this disadvantage and to expediently replace the severing of the membrane effected by movable mechanical means.
Erfindungsgemäss wird die gestellte Aufgabe durch einen Be¬ hälter gelöst, welcher sich nach dem Wortlaut des Anspruchs 1 auszeichnet. Vorteilhafte Weiterbildungen des erfindungs- gemässen Behälters sind durch die Merkmale der Ansprüche 2 bis 8 gekennzeichnet.According to the invention, the object is achieved by a container which is distinguished by the wording of claim 1. Advantageous further developments of the container according to the invention are characterized by the features of claims 2 to 8.
Der erfindungsgemässe Behälter wird beispielhaft anhand der Zeichnung näher erläutert. Diese zeigt inThe container according to the invention is explained in more detail by way of example with reference to the drawing. This shows in
Fig.1 einen Behälter mit topffδrmiger Membran und in Fig.2 einen Behälter mit geschwächter Zone als Soll¬ bruchstelle.1 shows a container with a pot-shaped membrane and in FIG. 2 shows a container with a weakened zone as a predetermined breaking point.
Gemäss Figur 1 enthält der erfindungsgemässe Behälter 10 eine topffδrmige, an der der Innenwand 11 des Behälters 10 zugekehrten Seite mit einer Klebenaht 21 versehene und an der Innenwand 11 des Behälters 10 befestigte Membran 20, wodurch zwei Kammern 30,31 gebildet werden, ein Ventil 12 und gegebenenfalls am Boden einen Stopfen 13 zum Befüllen der Kammer 31 mit einer Komponente und Druckgas: Die andere Kammer 30 wird über das Ventil 12 mit Druckgas befüllt, nachdem die andere Komponente eingebracht wurde. Während der Lagerung des Behälters 10 herrscht in einer Kammer 30 stets ein Druck, der höher ist als jener der anderen Kammer 31. Der die Mischung der Komponenten ermöglichende Durch- bruch der Membran 20 erfolgt durch eine auf diese wirkende Kraft, welche durch eine der ursprünglichen Druckdifferenz entgegengesetzten Druckdifferenz zustande kommt. Durch kurzzeitiges Betätigen des Ventils 12 wird der Ueberdruck der ersten Kammer 30 soweit abgebaut, dass die Membran 20 durch die nun umgekehrt wirkende Kraft des Drucks z.B. an ihrer Klebenaht 21 abgeschält oder an einer als Sollbruch- stelle wirkenden geschwächten Zone 25 aufgerissen wird.According to FIG. 1, the container 10 according to the invention contains a pot-shaped membrane 20, on the side facing the inner wall 11 of the container 10, which is provided with an adhesive seam 21 and is fastened to the inner wall 11 of the container 10, thereby forming two chambers 30, 31, a valve 12 and, if necessary, a plug 13 on the bottom for filling the chamber 31 with one component and compressed gas: the other chamber 30 is filled with compressed gas via the valve 12 after the other component has been introduced. During the storage of the container 10, there is always a pressure in one chamber 30 which is higher than that of the other chamber 31. The breakthrough of the membrane 20 which enables the mixing of the components takes place by a force acting thereon, which is caused by one of the original ones Pressure difference opposite pressure difference comes about. By brief actuation of the valve 12, the excess pressure of the first chamber 30 is reduced to such an extent that the membrane 20 is peeled off by the force of the pressure now acting in reverse, for example at its adhesive seam 21, or is torn open at a weakened zone 25 which acts as a predetermined breaking point.
Figur 2 zeigt im linken Teil einen Behälter 10 mit einer Sollbruchstelle als geschwächte Zone 25 im unaufgerissenen Zustand und im rechten Teil im aufgerissenen Zustand. Zum Oeffnen der Membran 20 an der Sollbruchstelle muss der Be¬ hälter vor Betätigung des Ventils 12 auf den Kopf gestellt werden; d.h. es muss sich die Kammer 30 unten, die Kammer 31 oben befinden. Beim Betätigen des Ventils 12 wird der Druck in der Kammer 31 so stark abgebaut, dass die Membran 20 dem Druck der Kammer 30 nicht mehr widerstehen kann und an der Sollbruchstelle reisst.FIG. 2 shows in the left part a container 10 with a predetermined breaking point as a weakened zone 25 in the open state and in the right part in the opened state. In order to open the membrane 20 at the predetermined breaking point, the container must be turned upside down before the valve 12 is actuated; i.e. Chamber 30 must be at the bottom, chamber 31 at the top. When the valve 12 is actuated, the pressure in the chamber 31 is reduced so much that the membrane 20 can no longer withstand the pressure in the chamber 30 and tears at the predetermined breaking point.
Nach dem Mischen, unterstützt durch Schütteln des Behälters 10 mit geöffneter Membran 20, kann das Produkt mit dem Druckmedium über das Ventil 12 ausgebracht werden. Dabei ist bei der Anordnung nach Figur 1 das Ventil 12 nach unten, bei der Anordnung nach Figur 2 nach oben gerichtet. After mixing, supported by shaking the container 10 with the membrane 20 open, the product with the pressure medium can be discharged via the valve 12. The valve 12 is directed downwards in the arrangement according to FIG. 1 and upwards in the arrangement according to FIG.
